Grounding resistance cabinet

Kufotokozera Kwachidule:

Ndi chitukuko chofulumira cha ma gridi amagetsi akumidzi ndi akumidzi, kusintha kwakukulu kwachitika mumtundu wa gridi yamagetsi, ndipo maukonde ogawa omwe amayendetsedwa ndi zingwe awonekera.The nthaka capacitance panopa chawonjezeka kwambiri.Pamene cholakwika cha gawo limodzi chikachitika m'dongosolo, pali zolakwika zochepa zomwe zingabwezeretsedwe.Ntchito kukana grounding njira osati amazolowera chitukuko chachikulu ndi kusintha zofunika gululi dziko langa mphamvu, komanso amachepetsa kutchinjiriza mlingo wa zida kufala mphamvu ndi giredi limodzi kapena awiri, kuchepetsa ndalama za gululi mphamvu wonse.Dulani cholakwikacho, chepetsani kuchuluka kwa resonance, ndikuwongolera chitetezo ndi kudalirika kwamagetsi.

Pakalipano, njira yokhazikitsira mfundo zosalowerera ndale kudzera mu kukana yalembedwa m'malamulo amakampani amagetsi.Muyezo wamakampani amagetsi DL/T620-1997 "Kuteteza kwamphamvu Kwambiri ndi Kulumikizana kwa Insulation kwa AC Electrical Installations" ikugwirizana ndi Gawo 3.1.4: "5~35KV imapangidwa makamaka ndi makina otumizira ndi kugawa magetsi opangidwa ndi mizere ya chingwe, pomwe imodzi. -Phase ground fault ili ndi capacitive current yayikulu, njira yochepetsera yotsika ingagwiritsidwe ntchito, koma kudalirika kwamagetsi, mphamvu yamagetsi osakhalitsa komanso osakhalitsa pazida zamagetsi pakawonongeka, ndi Impact pa kulumikizana kwa Relay chitetezo zofunikira zaukadaulo. ndi zokumana nazo zantchito zakomweko, ndi zina. ”Ndime 3.1.5 imati: "5KV ndi 10KV machitidwe ogawa magetsi ndi magetsi opangira magetsi, pamene gawo limodzi laling'ono la capacitor panopa ndi laling'ono, pofuna kupewa Kuwononga zipangizo monga resonance, gap, I arc grounding overvoltage, etc. ., ikhoza kukhazikitsidwa ndi kukana kwakukulu. "

Pamapangidwe ndi kusankha makabati okana, chonde onaninso: DL/780-2001 Distribution System Neutral Grounding Resistor Neutral Grounding Method ndi njira yomwe imaphatikizapo mulingo wa kutchinjiriza kwa mizere ndi zida, kusokoneza kulumikizana, kutetezedwa kwa relay ndi chitetezo chamagetsi chamagetsi. Chifukwa cha vuto lalikulu la kudalirika ndi zinthu zina, machitidwe opangira magetsi a dziko langa ndi makampani akuluakulu a mafakitale ndi migodi ndi osiyana.M'mbuyomu, ambiri aiwo adagwiritsa ntchito mawonekedwe osalowerera ndale komanso okhazikika ndi arc kupondereza ma coil.M'zaka zaposachedwa, chifukwa cha chitukuko cha mphamvu zamagetsi komanso kuchuluka kwa ogwiritsa ntchito magetsi, ma gridi ena akuchigawo ndi matauni alimbikitsa mwamphamvu njira yoyendetsera kukana.
